130 CORRYS WITH OR WITHOUT LAKE-BASINS. 



come to a cross break (<?), and it seems to be going 

 on more rapidly. 



Cooses Nos. 4 and 5 respectively are due to two 

 breaks that join at a little distance from the original 

 coast-line. In both cases the sea at first worked 

 along the breaks, but it is now also cutting out the 

 intervening mass of rock, slight deeps having been 

 formed at the junctions of the joints, evidently in 

 consequence of the broken rock being scooped out by 

 the back curl of the waves round the masses of rock 

 that stand at the entrances to the cooses. 



Coose No. 6 is an example of a single break (#, 

 fig. 11, PI. II.) along which the sea is working, and 

 forming a long wedge-shaped gut. 



Coose No. 1 is large, well-marked, and extensive, 

 being fully as big as many of the Kerry corrys. It 

 is about 4000 feet in diameter, a size that is greater 

 than many of the cooms in the larconnaught hills. 

 The formation of this coose is clearly dependent on 

 three breaks (#, b, and c, fig. 12, PI. II.), two of 

 which met at the old coast-line. It may be said 

 none of these are large enough to be classed as true 

 corrys. This we allow, but at the same time it is 

 evident that they are corrys in miniature ; and if the 

 sea had time enough to work, it would enlarge them 

 to any size. 



Cooses like that represented in No. 6 are not un- 

 common on coast-lines, while in the hills, cooms of
